nnsILInn'r WHEEL.

Application filed June 4,

. tion.

My invention relates to new and useful improvements in a resilient wheel, and more particularly to a solid web or disc wheel constructed of two cooperat ng discs the central portions of which are spaced apart and normally forced o r drawn toward each other by means of springs located between the discs or acting against portlons thereof on the outside, the springs in the latter case also engaging a sleeve or barrel suitably mounted on an axle provided with suitable bearing devices.

Another object of the invention is to provide a solid wheel web in lieu of the ordinary spokes and consisting of two. discs spaced apart at their central portions and converging toward their outer circumference, the outer portions belng securely fastened together in contact with each other.-

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I- will describe-its construction indetail, referring by numerals to the accompanying drawing forming'a part of this application,

. in which tions of the discs'in sectiontoillustrate their relation thereto.

In carrying outmy invention as here embodied, 2 and 3 represent two' discs which together form the solid wheel web and the outer portions of these discs are secured together in contact with each other by meansof rivets 4 or their equivalent and to the periphery of said d1scs is secured the wheel rim 5 inany suitable manner and said rim,

1821. Serial No. 474,997.

7 may be of any desirable construction, here represented as one to receive a demountable rim carrying the ordinary pneumatic tire.

From the inner part of the contacting portions said discs diverge toward their centers as plainly shown in Fig. 2 Where each has a hole therein with the edges turned in as indicated at 6 and these inturned edges have the collars 7 fixed thereto.

Passing through the .hole in the discs so 'that'said collars will slide thereon i'sa sleeve or barrel 8 preferably provided with a flange 9 at each end, said flange being formed as an integral part or separable therefrom as will be obvious.

The central portions of the discs are spaced apart but are normally forced or held toward each other by the tension of springs 10 located within a space between the discs and having their ends securely fixed to said discs but in place .of said springs 10 or in combination therewith other springs 11 may be used which are coiled about eachend of the sleeve 8 and interposed between the flanges 9 of said sleeve and the central portions of the discs or a component part thereof such as the collars 7 so as'to act upon the spaced portion of said mal positions, it being understood that said discs are of suitable spring metal so as to also tend to maintain their normal positions.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, What I claim as new and useful is 1. A wheel including a web consisting of two coacting discs secured together in direct contact adjacent their circumference and having-their central portions spaced apart, and springs producing a tension on said centralportions to normally move themtoward each other.

2. A wheel including a web consisting of two coacting discs secured together in direct contact adjacent their circumference and within the recess produced by their spaced having their central portions" spaced apart, and springs interposed between the discs portions, said springs being fixed to said discs to normally move them toward each other.

3. A wheel including a web consisting of two coacting discs secured together in direct contact adjacent their circumference and having their central portions spaced apart, and springs located exterior of the discs and acting on the central spaced portions to normally move them toward each other.

4. A wheel including a web consisting of two coacting discs secured together in direct contact adjacent their circumference and having their central portions spaced apart, springs within the recess between the discs fixed thereto, and other springs exterior of the disc, all of said springs acting on the spaced portions of the said discs to normally move them toward each other.

5. In a device of the character stated, a

sleeve carrying a flange at each end, a pair of discs forming a solid wheel web slidably mounted on said sleeve and having their central portions spaced apart, said discs converging toward their outer circumference with the outer portions indirect contact and fixed-to each other, a rim on the outeifl circumference of said discs, and springs tending to normally move the central portions of the discs toward each other.

6. The combination with a sleeve and a rim concentric therewith, of two discs secured together at their circumferences and attached to the rim with their central portions in spaced relation and coacting with.

the sleeve for sliding movement thereon, and springs housed by the discs and connected therewith for normally moving them toward each other.

In testimony whereof, I have hereunto aflixed my signature.
